Oracle Cloud NAT Gateway is a managed networking component within Oracle Cloud Infrastructure that enables private instances - those without public IP addresses - to initiate outbound connections to the internet or other OCI services, while preventing unsolicited inbound connections from the internet. Applications Manager's Oracle Cloud NAT Gateway monitor provides complete visibility into data transfer rates, packet handling, connection tracking, and availability metrics for your NAT gateways, helping you ensure optimal network performance and quickly identify potential bottlenecks.
Go to the Monitors Category View by clicking the Monitors tab. Click on the NAT Gateways available under Oracle Cloud in the Cloud Apps section. Displayed is the Oracle Cloud NAT Gateway bulk configuration view distributed into three tabs:
Clicking a monitor from the list will take you to the Oracle Cloud NAT Gateway dashboard, which consists of two tabs:
| Parameter | Description |
|---|---|
| GATEWAY INFORMATION | |
| Life Cycle State | The current state of the NAT gateway. Possible values: PROVISIONING, AVAILABLE, TERMINATING, TERMINATED. |
| Public IP Address | The IP address associated with the NAT gateway. |
| DATA TRAFFIC | |
| Rate of Incoming Data | The total data sent per minute from OCI resources to the NAT gateway (in MB/min). |
| Rate of Outgoing Data | The total data sent per minute from the NAT gateway to OCI resources (in MB/min). |
| Total Incoming Data | The total data sent from OCI resources to the NAT gateway (in MB). |
| Total Outgoing Data | The total data sent from the NAT gateway to OCI resources (in MB). |
| Total Data Transferred | The total data (incoming and outgoing) processed by the NAT gateway (in MB). |
| PACKET TRAFFIC | |
| Rate of Incoming Packets | The total packets sent per minute from OCI resources to the NAT gateway (in packets/min). |
| Rate of Outgoing Packets | The total packets sent per minute from the NAT gateway to OCI resources (in packets/min). |
| Total Incoming Packets | The total packets sent from OCI resources to the NAT gateway. |
| Total Outgoing Packets | The total packets sent from the NAT gateway to OCI resources. |
| Total Packets | The total packets (incoming and outgoing) processed by the NAT gateway. |
| PACKET DROPS | |
| Throttled Packet Drops | The total packets dropped due to throttling at the NAT gateway. |
| Port Exhaustion Packet Drops | The total packets dropped due to NAT port exhaustion. |
| Other Packet Drops | The total packets dropped for other reasons such as closed TCP connections, connections not established, packet size exceeding the MTU, or destination unreachable. |
| Total Packet Drops | The total packet drops across all categories at the NAT gateway. |
| PACKET DROP RATE | |
| Packet Drop Rate | The percentage of packets dropped versus total packets processed by the NAT gateway (in %). |
| CONNECTIONS | |
| Established Connections | The total connections established through the NAT gateway. |
| Closed Connections | The total connections via the NAT gateway closed by the internet host. |
| Timed Out Connections | The total connections closed by the NAT gateway due to idle timeout. |
| Parameter | Description |
|---|---|
| CONFIGURATION | |
| Compartment OCID | The OCID of the compartment that contains the NAT gateway. |
| Public IP OCID | The OCID of the public IP address associated with the NAT gateway. |
| Route Table | The OCID of the route table used by the NAT gateway. |
| VCN OCID | The OCID of the VCN the NAT gateway belongs to. |
| Created Time | The date and time the NAT gateway was created. |
| Traffic Blocked | Indicates whether the NAT gateway blocks traffic through it. Possible values: Yes/No. |
It allows us to track crucial metrics such as response times, resource utilization, error rates, and transaction performance. The real-time monitoring alerts promptly notify us of any issues or anomalies, enabling us to take immediate action.
